It seems that using SmartStore causes the app to freeze when installing an app for the first time, then a hard reset of the device is required. After that, the app seems to work fine. I experienced this both on my production app and when testing on the SmartStore Explorer sample app. Loading a fresh install of the same app on to iOS 8.2 has no issues.
I believe it is related to SmartStore because I do not receive any console logs on soup registration success or error, which I do receive when testing my app in iOS 8.2.
forceios version: 3.1.1
iOS: 8.3 (freezes on fresh install of app)
iOS: 8.2 (works fine)
App Type: Both hybrid_remote and hybrid_local seem to have the same issues (my app is remote, SmartStore Explorer is local)
Device: Mostly using iPad, experienced the freezing issue on an iPhone with iOS 8.3 also
